Within the framework of our thesis we presented the development of mathematical models and hydraulic systems of different structure. In doing so, we used a combined approach to modeling. In the construction of models we also performed measurements that were performed on a real system, namely on the AMIRA DTS 200 pilot device.
The work is organized as follows. In the first section we described the motivation for this task and the basic modeling methods.
Chapters 2 to 6 describe the five differently defined problems of hydraulic systems modeling, that differ in the order and number of input or output signals.
In the second section, we presented and described mathematical modeling of the first order hydraulic system in a series of typical design steps. The modeling results are actually two, a non-linear and linearized model that describe the performance of the system near the selected operating conditions. The following sections describes the experiments made and the development of nonlinear models for a univariable second and third-order system and for a multivariable third-order system. We have not implemented linearization in modeling these systems.
All developed models and measurements can be viewed in a user-friendly way with the help of a developed graphical interface, and because of their transparency it also allows easy continuation of work, both in the context of modeling and control planning.
